MACKIE MIX8 with adapter (Mackie)

This is a MACKIE MIX8.

I purchased it for my own studio a long time ago, but it was not used.
Someone else used it, so
I believe it probably works, but
since I have not confirmed its operation and
it is a product purchased a long time ago,
I am listing it as a junk item.
If it does not work, please understand that it is due to vibrations during transport, aging, or other various troubles and malfunctions.
Therefore, please no returns.

Please only purchase if you understand the above.
